Re: [Freesurfer] Tumor Segmentation in FreeSurfer
Hi Mohammed we don't explicitly label tumor as part of recon-all. Although several people here have some experience with tumor segmentation, we don't have nay public tools for doing so. cheers Bruce On Wed, 23 Apr 2014, Mohammed Goryawala wrote: Hello, I am reposting this question since I have not received any feedback with this issue.

[Freesurfer] Subfields on 1.5 Tesla
Hi Koen FreeSurfers: I have received a manuscript to review for possible publication. The authors have used the subfields algorithm on 1.5T scans and obtained a parcellation with values. They have drawn some major conclusions on the basis of the findings. My understanding is that this method can only be done on 3T. Is the 1.5T results valid? Please advice. thanks, Alan Francis ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

[Freesurfer] mri_glmfit | constructing the C.txt and FSGD files
Hi all, I'm trying to run what should be a very simple cortical thickness regression analysis in mri_glmfit, but could use some help with putting together my C.txt and FSGD files. I have two classes (e.g. Patient, Control) and two nuisance variables (i.e. Age, Gender). My FSGD file looks like this: GroupDescriptorFile 1 Title FS_Thickness Class Patient Class Control Variables Age Gender Input 130725_GB49NP Patient 18 1 Input 130620_HU64KP Patient 21 2 ... And my C.txt file looks like: 1 -1 0 0 0 0 ...which I'm pretty sure is wrong, but I don't quite understand what the columns mean, so any light shed would be appreciated! -Justin smime.p7s Description: S/MIME cryptographic signature ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

Re: [Freesurfer] mri_glmfit | constructing the C.txt and FSGD files
Your coding for gender is probably wrong. The way you have it set up, you are saying that gender#2 should have twice the thickness of gender #1. You should set up 4 classes (PM, PF, CM, CF) On 04/23/2014 03:40 PM, Baker, Justin T.,M.D.,Ph.D. wrote: Hi all, I'm trying to run what should be a very simple cortical thickness regression analysis in mri_glmfit, but could use some help with putting together my C.txt and FSGD files.

[Freesurfer] Applying a precomputed transform matrix to an image in free surfer
Hello, I’m having a volume (e.g. dtifit_FA.nii.gz) and a transform matrix (e.g. diff2anatorig.bbr.mat), and I want to apply the transform matrix to the image and generate a transformed image. This is a general question I’m having, but in this particular case, I want to apply the transform matrix (from diffusion space to the anatomical space generated by TRACULA) to the FA map to generate a transformed FA map that can be overlaid on the anatomical images. I wonder if I have to use mri_vol2vol command for doing this, and I don’t know how to provide it with appropriate flags. I’m already having the transform matrix generated by TRACULA (and I don’t want to change it; I just want to apply it to the image!). My crude guess would be something like this: mri_vol2vol --mov address of dtifit_FA.nii.gz --o address of transformed_dtifit_FA.nii.gz --reg diff2anatorig.bbr.mat Please let me know how I should run this command. Thank you very much, Emad P.S. I know that for this particular example, I can use the anatomical images in dlabel/diff, but the point for me is to learn how to apply a transform matrix to an image and generate a transformed image in freesurfer Emad Ahmadi, MD --- Postdoc Research Fellow Department of Radiology Massachusetts General Hospital Harvard Medical School 25 New Chardon Street, Suite 400 Boston, MA 02114 Tel: 617 726 5237 Email: e...@nmr.mgh.harvard.edu___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

Re: [Freesurfer] Applying a precomputed transform matrix to an image in free surfer
That command is right but add --fstarg or --targ $SUBJECTS_DIR/subject/mri/orig.mgz (they will do the same thing, one is just easier but more obscure than the other) doug On 04/23/2014 04:22 PM, Emad Ahmadi wrote: Hello, I’m having a volume (e.g. dtifit_FA.nii.gz) and a transform matrix (e.g. diff2anatorig.bbr.mat), and I want to apply the transform matrix to the image and generate a transformed image.

[Freesurfer] recon-all subject -qcache in a different version of freesurfer?
Dear Freesurfer experts, I have processed my images and done analysis with cortical thickness using FS510. Now that I want to do vertex-wise analysis with surface area and volume, I learned that there is a bug in FS510 with this. ( https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2011-August/019903.html ) Before I go on to use recon-all subject -qcache in FS530 to generate vertex-wise surface area and volume maps, I want to make sure that this would not cause concerns about use of mixed versions of Freesurfer, or concerns about interpreting my cortical thickness and surface area/volume findings together. And if it does, what should I do?
